Ability to provide WinningParty further information

Need for ability to specify for the WinningParty:

• its size (ie. from codelist: "Micro", "Small", "Medium" ...),
• nationalities of its shareholders/owners (ie. an optional, however repeatable element using codes),
• whether the organization is listed on a Regulated Market.

Should this preferably be at the WinningParty level only or may this also be of interest for any Party?
